Rom hacking

Found an interesting website this morning which is located over at http://www.romhacking.net
We all know what game roms are, but did you know that they can be patched to change or modify the game in small ways or even to a completely new game? Armed with an original clean game rom, .ips patch and a patcher program, you too can patch your roms so you can play Super Mario World all over again but with subtle differences in player graphics or even a whole new map!

Not just Nintendo either, if you check the the links I have posted below, you will see many different patches for all the most famous console games, pretty impressive stuff. Below is a video I found on YouTube that shows just how easy it is to create your very own Mario game with the right tools :)
